When one succumbs to hypothermia as this poor gentleman did here, the heart's conduction system changes in such a way that distinctive EKG changes are produced. When these are seen in the course of taking care of a hypothermic patient they should prompt aggressive rewarming techniques, but also, should prompt the treatment team to be gentle, as cold hearts are particularly susceptible to dangerous arrhythmias. "J" or "Osborne waves" are present here right on the heels of the QRS. These disappear with rewarming. Welcome to Miami.
